I installed fresh copy oem of xp-pro. (700mz, 192 ram 10 gig hd)I updated everything, thin trouble started. reboots and when sending error message reboots. I now have reformated and with no updates is running ok. I would like to update as far as I can without auto rebotting or eror screen and don't know which direction to go
